Data-storage firm Brocade said its shareholders will end up holding 70% of the combined company's stock. The deal, which is to be tax-free to holders of Broomfield, Colo.-based McData, will have McData holders getting 0.75 Brocade shares for each McData share owned. Both companies have struggled lately, with shares losing more than 80% of their value since a peak in January 2002.

"Today marks an important milestone in Brocade's continued success as a strategic provider to the enterprise customer," said Brocade chief Michael Klayko. "This combination will accelerate the pace of innovation, enable us to build stronger relationships with our customers and partners, and provide greater scale and efficiencies to accelerate our growth. We believe this is a strategic combination that will benefit our customers and create value for our combined stockholders."

We look forward to providing you with the full details of our financial results, which reflect Sonus' leadership position and growing profitability."
